Brain death in humans is normally considered irreversible. Even if you keep the body running, those damaged brain cells just won't recover to the point where you get a fully functioning person again. However, that isn't stopping Dr. Himanshu Bansal and his partners at Bioquark and Revita Life Sciences. They recently received approval from American and Indian review boards to conduct a trial aimed at eventually reversing brain death in humans. The initial, months-long test will use multiple techniques to try and regenerate brains in 20 patients, including lasers, nerve stimulation and injections of both peptides as well as stem cells.
